E3DC to Home Assistant

This is a custom configuration for Home Assistant to read data from an E3DC device via ModBus.

Installation

Copy on your Home Assistant server the folder packages at the same level of the configuration.yaml file.

For a better overview, you can create a subfolder e3dc under the packages folder and copy the files there. Is recommended.

Configuration

Add the following line to your configuration.yaml file:

homeassistant:
  packages: !include_dir_merge_named packages/

Edit the file packages/modbus.yaml and add your E3DC device IP address.

Extra Config

If you want to add utility_meter for creating daily/weekly/monthly sensors for better graphs or exporting to prometheus you can add the the file extras/utility_meter.yaml into the packages folder.

Usage

Restart Home Assistant and you will find the sensors in the e3dc entity. Now you can use them in your automations or add the sensors to your dashboard. If your add HACS to your Home Assistant, you can add the Layout called Power-Distribution-Card

To Add the Sensor to your Energy Dashboard use the following Sensors:

It is normal that some sensors are not available. This is because the E3DC device has not yet sent all the values. This can take up to 2 days.

Sensors

The following sensors are available:

• e3dc_grid_export_power - Grid Export Power in Watt
• e3dc_grid_import_power - Grid Import Power in Watt
• e3dc_battery_charge_power - Battery Charge Power in Watt
• e3dc_battery_discharge_power - Battery Discharge Power in Watt
• e3dc_autarky - Autarky in % per day
